CyberQ Wifi E-Mail Alert

I just got my new CyberQ WiFi up and running. The last thing I set up was e-mail alerts.

When I use the Optonline (my ISP) SMTP server, the alert e-mails had only a header, with no body, which meant no alert information.
When I use the Yahoo SMTP server (where I have an account), the alert e-mails go through fine.
